Question 1 Wayne Arthurs painful exit A freakish reaction to a pain-killing injection for a strained hip caused Wayne Arthurs sad Australian Open farewell yesterday. I think Wayne was given indications as to the risks and beneþ ts of this procedure. It s an extreme measure to take in sport, such as tennis where these sort of injuries can occur, he said. Obviously, the circumstances we discussed with Wayne last night, were exceptional. It was potentially his last match in his home country in a grand slam. said Dr Tim Wood, Australian Open Chief Medical OfÞ cer.

17 PHYSED EXAM Question 13 Captain Ricky Ponting has rejected suggestions Australia s heavy training during the one-day series left it with an empty petrol tank and led to its collapse in the Þ nals. Australia appeared ß at and fatigued in crashing to a 2-0 defeat to England at the weekend, having sweated through rigorous pre-world Cup Þ tness training during much of January. One of Australia s top AIS sports scientists, Dr David Pyne, helped Cricket Australia devise the loading-taper training. But he predicted yesterday it would now be looking at freshening up the players. They would be mindful of (getting ß at). Obviously it can be a combination of things: physical fatigue, mental fatigue, where they re at with strategies for the various competitions, Dr Pyne said. The coaches will go through their checklists and ask are the players fatigued, how do we unload them, how we can optimise their recovery? That s an issue they would be looking at right now, I guess.

List two speciþc signs of physical or mental fatigue that the coach of the Australian team might have observed if the players were suffering from overtraining. b. Outline one strategy that could be used to prevent overtraining. Athletes sometimes use training logs to monitor their progress. c.
